Peace had broken out in the Tory Party over Brexit although, given past form, by lunchtime today, when the leading figures have shuffled through the TV studios, hostilities may well have broken out again.

The leading Tory Brexiteer Jacob Rees-Mogg is reserving judgment on a plan which would effectively keep the UK in the single market, something he has described in the past as an unbreachable red line. The EU has cautiously welcomed the "common rulebook" proposal – at last, the leading negotiator Michel Barnier might have added – until he sees the fine print and until what must be the final negotiations begin.

The European Court of Justice would continue to have a say over UK trade, another Brexiteer red line, as is May's suggestion that EU citizens could be given preferential rights to come to the UK under a "mobility framework". And the settling of the Irish border issue is still as opaque as ever.

It is difficult to be optimistic, although the Sunday Herald welcomes it as a decent second best to another referendum on the final terms, the prospect of which seems now out of sight. May has at last faced up to her tormentors, although it is her back she should be concerned about. And Labour must now surely come out of the corner in which it has been cowering to ensure that this – not the best possible but the least worst deal – is carried through in the Commons.
